My invention relates to improvem., tsin roller side bearings for railwaycars'."

The objectof-myf-inrentioni ishto pr y yovide a. roller side bearingk fi-af'strong, simple, 'elficient and-durableconstruction composed of few parts, and,` wbiohwill provide.A for an extended travely or swing of the truck' and body holsters' in respect` toeach other.

The roller side-bearing embodying .my invention comprises in "coperativencombinaf' tion an upper bearing plate or shoe ixed to, the body bolster, a lower bearing plate fixed to the truck bolster, an anti-friction roller peripherally engaging the upper bearing *late* and having trunnions of reduced v diameter rolling upon the lowerv bearine 2lpl'ate, Amovable, 'followers engaging said trunnions; and springs inter osedrbet-ween said followers and the ends o the chambers in lower bearing plate in which the springs tit.V

My invention also consists in the novel construction of parts and devices and'in the novel combinations of parte and devices yherein shown and `described and more particularly specilied in the claims.

ot a railway car' provided with my improved' roller side bearing.A Fig. 2 is a det iil elevation, partly in section, on line 2-2 of Fig. 3 of the lower bearing plate, roller and parts associated therewith. Fig. 3 is a plan View, partly in horizontal section, on line B4-3 of Fig. 2. Fig. 4- is a vertical section oli liney 4-4 ot' Fig. 3 and Fig. 5 is a detail perspective view of one of the followers.

In the drawing, A represents a body bolster-of a railway car` and B the truck bolster thereof.

I ,The lw`r-bearing plate D is Jfurnished truck bolster B and through which the bolts i.v pass, by which the lower bearing plate is secured to' the truck bolster. The bearing 'plate D y is provided with central slot D1 to receive the' roller E and with longitudinal chambers D2 to ecei've the trunnions E1 of the roller Ewhich are preferably formed integral with each other, but in a separate piene from the roller, the trunnions being in the nature ot a short shaft of tempered steel inserted through the roller. The bearing plate D hasupright sides or guides Z2 for the endsof the roller trunnions to fit betweenv and treads Z3 for the trunnions of the roller to roll upon, the treads 'als being preferably oftempered steel and in a separate piece and` removable from the bearing plate D, one of these treads or wearingplates (Z3 litting ateach end of the roller.

The followers F, preferably four in number. are-all alike and preferably ot' a gen- Aeral hollow, box-like shape, and provided each with a. concave or journal face f for engagement with the trunnion El of the roller E, and a projecting cylindrical stud 0r hub f1 to receive one end of the spring Gr and serve as a seat or guide therefor. The bearing plate D is provided with a corresponding stud or cylindrical hub dtto serve as a seat and support for a shoulder or stop f2 to engage the correspending shoulder or stop (l5 on the bearing plate D which limits the movement ot the follower and serves to hold the parts in assembled position. i

In my improved 'roller side bearing, when the load is relieved from the roller and the springs act to return the roller to central position, the concave or journal tace et the followers acting against the trunnions oier greater friction to the turning of the roller than that of the periphery of tle roller against thebearing plate, which as the weio'htof the roller only to produce traction or ipriction, and. as a consequence the roller is to a orrester or less extent returned to with depending lugs (l1 fitting astride the.

In this connection, it will be uiiderstood that thetension of the springs is very much greater than the weight of .the roller after being compressed by the swinging movement of one of the holsters in respect to. the other. The concave faces of ,the Ifollowers thus act likey 1. In a roller side bearing forrailway cars, the combination with an'upper bearing plate fixed to thebody bolster, of a lower bearing plate fixed to the truck bolster, a roller extending transversely across said bearing plates and engaging the upper beary ing plate and having' trunnions of reduced' 25' pair of independently, separately, movdiameter engaging the lower bearing plate',

able followers engaging each trunnion on oppositesides ythereof and .springs inter-- posed between each of said followers and said lower bearing plate, each of said followers having a concave face engaging a trunnion of the roller, substantially as specified.
